Step 7: Assembly!

Step 8: DONE! How to load and fire

A. Pull the hammer back. It should be easy, especially with the new handle. B. The trigger should pop up into the slot, effectively and smoothly block...

SR70A1 Precision Sniper Rifle System. Great range, accurate, powerful, versatile, you name it.
It is a ramrod rifle. It uses #64 rubber bands, and looks great.

Also, I have now made a folding bipod for this gun. Now all I need is a hammer/firing pin guide because at 5+ bands, the black rod begins to bend and break. In other words, I need something like the Z35's guide.

Pros
Ramrod rifle
No jams if made correctly
Easy-detach scope and barrels
Smooth True Trigger
Fires any rod
No mags
Any accessory can be attached
Lefty support
Comfortable
Scope with dot sight; accurate.

Cons
May be too small for some people
No mags
Grip may be uncomfortable for big hands
Barrel can droop, but fixed by a rubber band.
Well...that's all I can think of.

I built this a month ago. But the barrel is too high friction. My bullets wont even come out of the barrel. I figured out a way to reduce the friction in a barrel. First, take a drill and one your pieces. Then run the bit around the hole of the piece to make the hole slightly bigger. Ta-da!

Sorry, my pieces' holes must be smaller. I haven't built a gun that works before that has that kind of barrel. A few days ago I built a gun with a zero friction barrel with the Z35 rear barrel, mag,and the SR70A1 PSRS trigger and scope. It shot about 10 ft : (

Dude guess what? I built this again and it WORKS! But the only problem is, I think I dry fired it, I had a second transfer rod behind the original ( red rod ), the grey one shot through the gray clip, then the red rod went into the gray clip!!! Any way to fix it?!

Take off the rubber bands, hammer, and the scope. Undo the barrel support that's directly below the hammer. Then, pull the entire barrel off the stock. Disassemble the barrel from the muzzl (This might take a lot of effort) and replace the broken pieces. Reassemble the barrel, and follow the instructables on how to reassemble.

The piece actually not broken, but I fixed it an easier way. I just took off a blue that held the grey clip that holds the transfer rod. And also, I kind of screwed it up by building it wrong so I had to add a red rod and a yellow rod.

I haven't counted, because I modified the gun to be so rock solid that I can't take it apart...

But the point is, the gun depends on the hole in the middle of the white connectors to function. That's what makes up the barrel of the gun. If you replace them with blue connectors, you'll be blocking the barrel.So, you really shouldn't replace ANY of the white connectors with blue connectors. The only white connector I see that can be replaced without compromising safety and performance would be the ones on the faceguard/stock.

NO. No ball joints in the barrel, EVER. This will break it, no exceptions.

Sorry, Firefox, Chrome and IE9 are all malfunctioning at once. Can't add notes.

That would be a gray connector. DO NOT USE THE OLD ONE FOR ANY REASONS. IT WILL SHATTER THIS CONNECTOR. This gray connector has been covered with electrical tape on the SIDES (not the faces, where there's holes and make the connector thicker). The tape should be applied after the gray rod has been clipped onto it, and it should reach around the clip.

I hate those square guns. Makes guns look blocky (perfect for Glocks). Rifles and real barrels have a circular barrel, not some square blob with a hole on it. This is as close as you can get to a circular barrel.
